Conversion from Unigraphics to CATProduct is not supported yet :(

Unigraphics is a former name for Siemens NX, an advanced CAD/CAM/CAE software application suite. However, veterans are still using the Unigraphics name.

In 2002, the new version of Siemens Unigraphics, merged with I-DEAS software, was released and called NX, which means "Next Generation". In fact, it was the last version of the software released under the Unigraphics name. All further releases became known as NX. So the addition of I-DEAS functionality to the core code of the Unigraphics has become the basis of the existing NX product line.

Siemens NX / Unigraphics use a .prt extension, which contains 3D CAD parts.

The CATProduct file format is associated with CATIA V5 assembly format and is used to simulate industrial design processes.

Unlike CATPart files, CATProduct does not contain any geometric information, only model parts, and assembly structure information. Nevertheless, single CATPart files can be generated from CATProduct assembly.

The CATPart extension is compatible with Autodesk Inventor / Fusion 360, and Okino Computer PolyTrans software.
